Engine loom on 993
Discussion
Just had the ominous 'good and bad news' phone call from the garage servicing the 993.
Engine loom has shorted and causing all my little electrical probs. Apparantly very common on 993s (although not this bad usually) and lucky not to have caused an engine fire!!
That was the bad news, good news is they thought it was a '£500 only available ordered from Germany' part but are in fact only £200 and AFN have two on the shelf... Guess that's good really compared with the alternatives.
Worth checking by anyone else with a 993 by the sound of it.
Word of warning

RR - some of those apply to the 993TT only. First gear problems and turbo leaks (doh!) don't apply to the rest of the range, if I remember.
Cracking front windscreens I have heard of, but loom is an interesting one.
I also heard from a dealer today that early 996s can be troublesome, and that a late 993 can make much more sense....

I've heard about the wiring problem - it is very common, and its worth having you car checked if it hasn't had it done.
The first gear thing, only applies to the Turbo, and ONLY if its been dragged raced (ie in the US of A). Normal driving (or even spirited driving) won't harm it.
I've also heard of the rear window can suddenly smash due to body movement, but have never met anyone who's had this problem.
Other than that nothing out of the ordinary to look out for. If you've got the Turbo (not sure where it also applies ot the C4) get the geometry checked every now and then as it gets nocked out quite easily).

I too have a 95 993 and have just had my car back for two weeks after getting the Loom changed.
It took eight weeks for the mecahnic to find the fault and fix it.(I had to ask him to check the Loom)
Follow this link, this guy has been trying to get the US trading standards onto Porsche as so many have failed. I think they have just thrown the case out, but the site has loads of info etc.

Mine came to about £1000 after having the ECU rebuilt and one new injector fitted.
My symptoms where loads of overfueling (Missing/fumes through exhaust) and a flat battery.
I would recommend if you have a 95 car to get this checked. The looms where substandard and crack and short out. I could not understand why for about a month my car smelt of burning rubber, everytime I drove it ; o)
When I got the old loom I was quite shocked to see that all the wires to the injectors where split and had been arcing across each other.
Anyway all is well now. Above site has chassis numbers that are affected etc, so go and have a look.

Cheers Grant,
All very interesting (if not a bit depressing) stuff. Just spoken to the garage and they've just finished the job and were about to take it for a test drive. Total git of a job, have to rewire all the injectors, starter motor (which is the main danger point as you have a huge permanent live feed) and even the alternator has to come out (I've done one of these myself in a 3.2 Carrera - nasty nasty job) and be rewired.
He agrees with the web site that these have been replaced many times under warranty and that even though my car is out of warranty it's worth a stroppy letter to their customer services department.
Anyone had any experience of this or similar?

Well I have my Loom, and I was going to fire a letter of with the dirty loom (cover it in a bit more oil first) to Porsche and see if they will do anything, only problem is I don't have an address ??
Its worth it to try and get something out of them.
Which garage do you use as they seem to know their stuff, and Iam after someone a bit better than I have been using.

I use Northway Porsche. (chap called Ray Northway runs it) - they're a good outfit who certainly know their stuff - All official Porsche trained. they appear very rough and ready (you'll get no fluffy door mats and cups of posh coffee to greet you) but they'll do you favours if they can and will often use their nonse to sort a prob if poss. He's charging me 1½ hours labour to remove the old loom and 2½ to put the new one in (and I know it's a real sod of a job). Nothing much to find and diagnose the prob as he knew quite quickly what it was. Only about £35 per hour too, makes those cups of coffee seem less appealing when the guy in the suit hand you a £2k bill!!!
I've taken each of my last six Porkers there and have always been impressed. There is a price to pay - they are bloody busy (about a month waiting list to get a service) but again will always help you if they can (ie: I was only booked in for a service yesterday and they found this. Ordered the part yesterday afternoon and fitted it for me today).
Hope he sees his free PR here and 'forget' to now bill me
