Thought it was about time I made one of these, unfortunately last year with an imminent house move and our first little one on the way, the decision was taken to part out my mk1 MX-5 - which I'd had for 6 years, after winning it in a bonus ball competition for the total sum of £20.00: lots done, lots spent, by the time it was split it was running a GT2554R turbo - so roughly 250bhp.

With the Mazda parted out, move completed and new member of the family arrived safely - in January this year I started looking again at what could fill the empty spot on the driveway, rough criteria was: fun, practical (5 door),child friendly (isofix) and safe (Mazda had no airbags). Many options considered ranging from Octavia VRS, Focus ST Estates, Polo GTI, all the way up to an Audi TTS for a very brief moment. In the end RWD and non-turbo were added to the list, so we landed on a BMW 130i, which I'd flirted with getting many years before but had unfortunately bought a lemon of an Audi S3 instead. Couple weeks looking at what was available in budget, few enquiries made, eventually found a tidy example with a decent list of recent preventative maintenance - so train ticket in hand and a trip down to Blackpool for a closer look - in typical fashion I bought the first example I looked at.

So what did I buy? it's 55' plate pre LCI BMW 130i with 109k miles on it, the one with the hydraulic steering and the N52 engine , has most of the options I wanted: Xenon's, heated seats, rear parking sensors, but no sunroof unfortunately, someone has already ditched the run flat tyres and fitted some spacers with freshly powder coated wheels. Recent maintenance being: oil filter housing gasket, A/C compressor, starter motor, new brakes all round, water pump in the last 4 years, DISA valves have been checked and Vanos solenoids cleaned. Bad points: base audio, no cruise control, one spot of rust on the drivers wing (5p in size), slight wobble at motorway speeds (sold as a suspected wheel balancing issue), radio has dead pixels when hot and a Radiohead CD inside with only 4 songs that don't skip - nothing too bad that can't be fixed.

It's to be used primarily as my main commuter but also as a fun second family car that the wife can drive, all maintenance to be carried out by myself where possible. I'll do another update bringing everything up to speed- but thoroughly enjoying the large engine/small car format and my first foray into BMW ownership.

Nice one. My previous car was an E81 130i that I made some great upgrades to the suspension, brakes and wheels, and the interior.

I think my next car will need to be a five-door hatch and I could see an E87 130i working. Lots of character these cars, especially with some changes to the exhaust.

Lovely car, and with the rare xenons. Sounds well sorted so you should have some trouble free motoring.

Nice one! I picked up a Le Mans blue one a few months ago as I needed a practical family car.

Just had sump gasket, oil filter gasket and some other bits done. Mine had B12s on it which I am ditching next month...

Also I got rid of the M Sport steering wheel as I hated it - way too thick and robbed feel. Stuck one on from a same era 320d SE. Loads better IMO!

May look to get some Recaros in it after my suspension change. Some engine and exhaust work may be on the cards after that.

Great cars!

Nice.

My 130i LE was one of the favourite cars that I’ve owned. With hindsight I shindig have swapped my wife’s 125i cab for something more practical and kept it. Mine was on Birds B1 suspension to which I added M3 LCA’s and camber plates. It was a lot of fun to drive. Changing the gearbox oil, changing the white shifter bush and binning the CDV improved the gear change no end.

If you can find one for sensible cash, the 135i back box improves exhaust note too.

I needed the 5 doors or I would have looked at the E81/E82, but for what it is I'm thoroughly enjoying it so far. I'll go into more detail but I've already had to sort out the front brakes and the exhausts had some work.

Thanks, yeah that was the idea but as with any car there's always little things that need sorted out, some big things also.

The wife has only commented so far that the steering is really heavy, unfortunately she doesn't appreciate the benefits of hydraulic steering.

I thought I was on stiffer suspension the rides that firm, but they're B4 so I can only imagine how bad B12 must be. How much was the sump gasket change? I've since found mine also has a leak - wondering whether to do it or put it into a garage.

I was trying to find out if I've got the LCA's already, the camber pin mods been done already. Gearbox oil changed and the white shifter bush is on order, CDV was deleted not long after I got it - just could not get on with the gearchange delay. Ended up opening up the stock box and blocking off some of the chambers for a bit more sound - horrible job but sounds great.

Fantastic car. thumbup

That's what I should have bought in 2019 but I was too mean with the budget, so I got a 2005 E90 330i instead. rolleyes

Still it has the same drivetrain, including HPAS, and mine has Xenons, cruise and electric glass sunroof, but no heated seats.

Over 5 years later I'm still loving it. biggrin

You did well finding one that already had a new water pump too as they aren't cheap. Just keep an eye on the cam-cover for leaks as the gaskets get brittle over time.

So with the car home in one piece, I started to look through what I'd bought, it's the highest mileage car I've owned to date on 109K and I would be owner number 7, so I was expecting to find some things needing attention, the engine wasn't due an oil change until July but I had no records of any of the other fluids having been changed -  so set about changing the Gearbox oil and it's rubber mounts, diff oil, power steering fluid and eventually the brake/clutch fluid. From looking at it the diff oil hadn't been changed in some time - whilst under there treated the rear subframe for corrosion, luckily the front subframe is aluminium so don't need to worry about it. Also fitted some BMW black front grilles and some wind deflectors:

These are by no means the prettiest car on the road, but I think the look of them is maturing nicely, but the rear lights really let down the whole aesthetic, so I picked up a set of LCI Low-darklines to update it a little - it's had a rear wiper delete at some point, that I'll need to un-delete as the shape of these the rear window it's forever dirty!

Next on the agenda was looking into the stock stereo setup, someone at some stage has upgraded the Business head unit to a Professional BMW unit, but all of the speakers were base audio/white stickers. Picked up a set of Hi-Fi speakers, subs and tweeters to help lift the experience - I will try to get an amp installed at some stage to boost these a bit as they still could use a little more punch.

20240217_170823 by Scott Reid, on Flickr

Couple of things in the interior required a bit of attention, firstly with the commuting miles this was going to do cruise control was a must, luckily with these this isn't a big job so that was sourced and installed by a local BMW guy. Some new cheap mats sourced as it didn't come with a full set, set of wind deflectors fitted as there's no sunroof, new pollen filter as it was smelling it's age -  I still need to wet vac the carpet as I found that made a huge difference in the Mazda. I still need to change the interior mirror as it seemingly burst internally and has lost all its mirror juice - but there is supposedly a lot more packaged in there so I need to find the correct part number first - a common theme with buying BMW parts!

The engine is an absolute peach but you can't really hear it inside - if I'm going to pay for the privilege of running a straight 6 I'd ideally like to hear it in all its glory. BMWPerformance exhausts seem to go for 1/5 of what I paid for the car so that wasn't going to be an option, instead I could either delete a resonator in the midpipe, delete the back box or modify the backbox internals to mimic the BMWP option. So with a second backbox sourced I set about cutting open 2 of the chambers, as it's a valved system each chamber goes to a different exhaust tip - covering the perforations effectively deleting the corresponding chamber - I run the exhaust flap unplugged so the flap is always open but if it proves to be drone at motorway speeds, I can plug it back in. in short the noise is far better for a fraction of the cost of a BMWP backbox - would highly recommend.

With all of that completed in time, I took it on a road trip around Scotland with a few friends for a night away - the only 5 seater in attendance, but it did surprisingly better than expected straight out of the box. A proper drive out highlighted some issues - the supposed wheel balancing wobble was most certainly a warped disc - this age of BMW has slider pins callipers which I've never gotten on with - the brakes had been in the last year or so but the calliper looked original - more on this in a future post. Another issue was a lack of starting once the car was hot -  no cranking, nothing. I knew the car had a melted distribution block that sits on top of the battery in the boot floor - I think someone has connected a sub here at some point and it's done a fair bit of damage - the previous owner had installed a new starter motor to fix this issue but it hadn't worked - but at least I've a new starter motor.

Car also went in for an airbag recall at BMW, hadn't quite realised an E87 is now quite a small car, compared to some of the newer Bavarian offerings.

We're almost up to date, but I'll save that for the rest for another post.

I almost got a 3 series in the past a couple times, I think if this proves too small a 3 series estate is on the cards. Thanks will do, I think it had a cam cover along with the filter housing gasket, but will keep an eye on everything. I think the next big jobs going to be the sump gasket as I don't want the small leak to become a big one anytime soon!

According to BMW the gearbox and differential are Sealed for Life so they often don't get fresh fluid. But I don't like that idea so I've had mine replaced anyway.

Based on my experience of my 123d I reckon a 1 Series definitely needs a rear wiper - on a wet drive the rear screen gets filthy.

My 330i has done 125K now and is still leaking oil despite fresh cam-cover and oil filter housing gaskets, so sump seems to be the only other possibility, but I'm trying to put it off by just topping up! Mainly for cost reasons as I think the front cross-member has to come off to remove the sump. But if you can DIY cost won't be huge, other than in time.

Lack of engine noise is something mine suffers from too. I've had the same engine in a Z4 and it sounded lovely. But they still get down the road pretty well when you get the chance!

Looks like you've had a great trip already - enjoy. thumbup

Watching with interest and the exhaust mod sounds like a good idea.

I just had the sump gasket done on my 130i as I wanted to just get everything done. Was quite a big job at a specialist.

Had 7 130i’s over the last 16yrs, from bmw main dealers purchases when they were new through to £1500 rough ones.

Always come back to them because of that engine, the n52 is a scorcher. I had a z4 with the m54 last year and I then got a yearning for a proper revvy 6 cylinder, picked up an LE for £2500 earlier this year, but then I realised as a third car it was not special enough. Plus it needed so much work doing due to neglect. Ended up with a 125i cab with same engine and mapped to 130i power. Mainly for road trips and it’s been cracking. The engine is the majority of the engine, roof down the standard exhaust is more rhan enough.


The 130i is pretty bullet proof, just a couple of known weak spots, the oil filter housing and rocker cover gaskets, it is a bmw so they like to leak which you have already done. The other main one is the water pump, if no evidence it’s been done I would treat as preventative maintenance along with a new thermostat as it will leave you stranded when it goes . Pierberg is the best and cheapest on Amazon oddly, done mine on the 125i back in July. Also starter motors but you do get some warning as they start to take a bit of effort to start before they go.


Oh and if keeping long term, then you need an LSD, transforms the car, I’ve only ever had qualifies, but the blackline is a qualify copy and loads run them, at £550 new worth it plus fitting. If you can get a second diff housing so come sale time you can simply swap and sell the lsd as a complete unit.

Xenon’s on them can be an eternal pain in the ass with ballasts going. I’ve alwayss preferred the halogen as they are bloody good out the box and zero maintenance.

Oh and brakes, don’t mess with 6 pots, pointless and actually pretty bad due to heat issues. Week out a set of 340mm 4 pot brembos from the m135i they work very very well

Great cars and they don’t make them like that anymore.

I love the N52 engines too!

After two Z4 Coupes with them I bought an E91 325i as a daily, but it was a bit lacking in grunt so after a year I replaced it with an E90 330i that I've had for over 5 years. They are a real bargain for what you get.

What mods do people do to these? I think they lack a bit of low rev torque and could do with a lot more induction and exhaust noise..

I think suspension mods and fitting an LSD seem to be pretty popular.

Sound-wise my 2nd Z4 with a custom cat-back exhaust sounded great!

I'm not sure how much can be done about low rev response with an N/A engine - just use a lower gear. laugh

Indeed, I think only an enthusiast would change now, but it did look like at least the gearbox had been done and wasn't 100k+ old. The sump didn't leave any oil on the driveway until the car had been sat front up doing maintenance. it's the gearbox end at the passenger side - seems to be a common occurrence on the manuals at least. DIY would be the goal, do the engine mounts at the same time, I'll get a cost from a specialist but I think that'll price itself out of contention.

I'll take a video and post a before and after video for those interested.

Do you have a rough price for the cost of changing the sump gasket by any chance please?

I had mine done at a BMW specialist. Think it was a day's labour so whatever that is where you are. I did a load of other stuff too so had a big bill.

Mine is now booked into Birds early September for the B1 dynamics package.

This is my family car for the next 10+ years so happy to chuck a load at it to get it to where I want.
