Problems with Laguna

[haggisswinger]

Can somebody please help! I bought a second hand laguna last week and have had no problems with it so far, apart from a juddering when the car is below 30 rpm, which appears to be associated with juddering of the speedometer. Once you reach 60 mph and above it is fine, appearing to level itself out.

anyway, i took the car to the renault dealer today, in the hopes that they would detect what the problem was so I could have it sorted out myself. I don't know what they've done to it, but now it won't start at all!! They don't seem to know what's happened and didn't appear to be overly concerned that the car was running fine until they got their hands on it. They mentioned pulling the spark plugs out and then putting them back in, but the car is no longer sparking ... could they have screwed the ECU system or does this sound like an immobiliser problem??

I hope somebody out there can help - I don't trust the dealer at all and am worried they are going to try and rip me off.

Thanks.

Hi Haggis

Sorry to hear about your problems. Bit puzzled why you bought the car if it had this problem - however that's another discussion point.

Regards your car and the dealer if the car was running when you took it in, it should be no worse when you get it back. I doubt the ECU would have an effect on your judder problem.

One of the difficulties with "forum diagnosis" is getting an accurate description of whats going on and in this case the juddering you mention is not well enough defined.

Any number of faults can cause a car not to start these days. One sensor wire disconnected can do it.

Be firm with the dealer. Tell them you want the car back in a running condition at no expense to you. If you only asked them to diagnose and not fix - they should do this. If they won't, threaten them with a nasty letter to Renault HQ informing then how bad the dealers service is. Then move on to legal action if that doesn't work.

Which dealer was it - so others don't get caught out!
