Last week a garage changed the clutch on the car. After 25 miles or so of driving an intermittent !Warning! EFI Fault' started to flash on the display. Parked car up for a couple of days, then took it out again. The fault only reappeared once the car was up to temp.

Took off the bonnet to see if it was anything obvious and noticed that the oil breather pipe was not connected at the oil resevior end - the pipe was just hanging down from the airbox in front of the engine.

The problem now is, after popping the pipe back on the EFI Fault is displayed permanently! I'm just hoping the garage didn't pull the pipe off in the hope that it solved the EFI Fault, little knowing that it would appear after the car got hot enough.

I have read a few posts where it may be something to do with the airbox not being installed properly. Can anyone offer any advice?

ps. I'm a little reluctant to return the car to the garage which did the work for a couple of reasons. One being it's quite far away and they'll probably hang on to the car for the next week or so. Another is they charged me over £1,500 to change the clutch and slave cylinder (charged about £300 more in parts than could've got them from TVR Power), and finally until I know they didn't just bodge the job by leaving the oil breather pipe on purpose, I'd rather not let them work any more on the car.

£1500 ?! I'd of done it private for half that wink
Could be a number of things, id be surprised if putting the pipe on actualy effected it. check the sensor on top of the air box, could be a number of things, so you need to get the laptop on it really !

Unless you've had this resolved it may well be the answer;

Thanks for your replies.

No, I haven't had the hole in the manifold fixed yet because I was only told about it as I got the car back from having the clutch done.

Just seems a bit of a coincidence that if it is the hole causing the EFI fault, that it only came to light a day after getting the car back, and not in the previous 6 months trouble free ownership of the car. Unless, is it possible that once an EFI fault is reset, it wont come back on again? Or will it do so if the fault still exists?

Anyway, checked all I can without a diagnotics cable. Car booked back into the garage now - been told it will take an hour or so to get the data off the car. Bloody hope they're not going to attempt to charge me for it!!

Depends what the fault is to if they charge you or not, in terms of what they would of had to remove to do the clutch;

-The whole airbox (inc air sensor)
-starter motor (possible could have damaged the water temp sensor/connector on the block while taking the bolts out
- prop/gearbox/ bell housing. (earth wire on the top bell housing bolt)
- clutch/flywheel/hydraulics

so there isnt really much else they could of got wrong, post up what they find though smile

Thanks Jamie, will do.

Wish I knew someone round here with the kit. Looked at getting a cable earlier this week until I realised my lap top doesn't have a serial port.

Turns out it was an air sensor fault and that the wire had broken away from the little plug.

All sorted now and back to normal!

Thanks for all your help smile
