BMW 330i (E92) | Shed of the Week

Six-cylinder, shaped like a bullet and shed-priced - rejoice?

As Mrs Shed will confirm, dynamism isn’t something that normally affects Shed, but an unwelcome dose of it interrupted his slumbers last week. Or at least, a dose of Oasis-style dynamic pricing did. Just as he was about to suggest this BMW 330i coupé as Shed of the Week, its price was rudely increased from just below his £2,000 limit to a SOTW-disqualifying £2.5k. Clearly someone with the ear of the vendor reckoned £2k wasn’t enough for one of the most powerful E90 Threes you could buy.

It seems that the buying public thought otherwise because now it’s back to £1,999 and therefore once again enmeshed in Shed’s slimy keep net.

The E90 was the last 3 Series range to include models you could buy without a turbocharger. The naturally aspirated N52/53 Valvetronic 3.0-litre inline six powering 330is like our shed was a lightweight aluminium and magnesium unit that sat well back in the chassis for more balanced handling. Shed has hedged his bets with ‘N52/N53’ there because there’s some confusion inside his warty old head as to whether a late ’06 330i will have the N52 or the N53 engine. This is relevant to the used E90 330i buyer because, although the direct injection N53 was more powerful than the N52, it was also potentially more problematic.

To add to Shed’s confusion, tinternet says that some N52 cars were still being registered in the UK in 2008 even though the N53 arrived on the 330i scene in 2007. Some maintain that the power output for the N52 varied according to the body shape, i.e. whether it was the E90/91 (saloon/estate) or slighty higher for the E92/93 (coupé/convertible). The ad for this coupé says 268hp at 6,600rpm, which would be about 40hp up on the E46 330i, with a torque figure of 236lb ft from 2,750-4,000rpm. The 330i weighed under 1,500kg, so even with the 6-speed auto fitted its 0-60mph time nearly started with a five. It actually did start with a five with the manual box, but the long lever throws on that could prove tiresome.

330i grip, steering, braking and general handling were all widely praised by the contemporary press. One unexpected 330i bonus, given its performance, was the combined fuel consumption figure of 37mpg, a number that was perfectly achievable without the requirement for driving shoes that were made out of butterfly wings. Because our shed was first registered in December ’06 it doesn’t fall into the mysterious Band K* rate for British vehicle duty. Happily, though, the engine efficiency of 175g/km keeps the annual tax bill affordable at £325.

This coupé has done 132,000 miles and has had the same owner for the last 8 years, which would have been good if the bod in question had been the fastidious type. At first sight it looks like they weren’t. This car looks a bit neglected. There again, there’s something weird about the MOT history that might excuse the current owner, namely the minuscule accumulation of miles over those 8 years, just 8,000 in total, with only a few hundred a year racked up since 2020. Maybe the neglect was perpetrated by previous owners and the last custodian had an unfulfilled plan to restore it.

The current MOT certificate to next February is not frightening but the comment about a slight tapping noise from the engine is. This indicates that it is the N52 we’re dealing with here because that tapping noise is almost always down to the N52’s hydraulic valve lifters being starved of oil from cold, leading to unhealthy metallic contacts between lifter and lobe. Left unattended this will result in broken parts and a big repair bill. If someone like Shed was selling the car he’d most likely ‘cure’ it by chucking some gloopier oil in and hoping that the buyer wouldn’t notice anything until it was too late. Owners with a longer-term view would hope that the cyilnder head was OK and turn their thoughts towards replacing the lifters. A full set of those will cost you under £200. You could perform the operation on your driveway but you’d need to set aside plenty of time and patience for it.

This is the problem with used cars. When cars are new they’re great, but when people use cars they become used and that’s not what you want when you’re buying a used car. When the E90 330i came out it was a sweet, fast and reliable drive, but that was twenty years ago. Now there’s a pretty lengthy list of common 330i issues including leaky oil filter housings, valve covers, sump pans and VANOS seals. VANOS solenoids, coils, electric water pumps, window regulators, door lock actuators, instrument clusters and central locking systems can all fritz out.

Batteries can drain, and diffs, driveshafts, suspension bushes and wheel bearings can all fail. Inside, you might encounter some stickiness with your climate control buttons. Air con systems could become a bit selective about when they would supply cold air, and starter fob slots occasionally blow out. We’re told that the bodywork is not prefect, but that’s good news because the bodywork on Shed’s Ford Prefect was awful even when it was new.
