ECU - where is it?

[Len]

Also for ECU related issues in the Deals & Discounts section there is a place offering 5% discount on testing.

Well VW have managed to get my car running and supposedly all they have done is to change the ecu relay.....unbelievably annoying as this is the first thing I tried before resorting to the garage as that has gone before. Whats the chance of buying a new faulty relay??

The previous garage tried everything with no luck so will find out tomorrow if this works...if it does it is the most expensive relay ever.

Well I spent nearly £300 before finding out it was the relay! How much did you spend?

Any other advance on 300?

so far Len the cost has been £150 (£100 for the garage and 50 for dizzy cap, leads) and the £8 for what might be a faulty relay! VW have phoned this morning and the car starts but they havent driven it which was what happened last time and it played up.

If it is the relay I will well p*ssed off as that was the first thing I changed....oh well at least it will be running. I reckon the bill from VW will be at least £150, so I may come close to your 300!!!

will keep you posted

Not heard of a faulty ECU relay preventing the car starting before so yea let us know.

Thanks to everyone on here when mine played up it only cost me the ECU temp relay

Len, several years ago I had an itermittitent problem where the car would cut out and then eventually the car just wouldnt start, it would just turn over - the cure for this was to replace the ecu relay so it is similar syptoms this time - just that the ecu relay made no difference this time when i replaced it.

still no word from VW so I think that the test drive showed up the problem

Hall sender, relay 30

Hall sender, relay 30

changed it but made no difference.

Well got car back from VW and it was the fuel pump relay......which I had bought and tried before taking it to the garage so not happy that it could be a faulty one I bought 

Grand total for two garages to sort the problem £272.00, plus the £40 I spent on leads and dizzy cap 
Going to try the relay I bought again at the weekend to check that it is faulty and is not just an intermittent fault elsewhere that may have cured itself temporarily. Not totally sorted cos now if you take the car over 5000 rpm it feels like it has hit the rev limiter....will have a search on here cos I remember a similar thread a while ago. Why is it these costs occur just as you are looking to sell your motor??

8v, if its hitting the limiter at 5000rpm its very likely its the timing belt thats out. Could be other things but in most threads this is the cause.

The same thing happened on mine. Timing was out, running lumpy and revving to 5000. After adjusting all has been fine.
