Car Forum / Jaguar Cars / October 2005Jaguar XJ8 - Rough Idling
My workshop checked my car thoroughly and could not find what is causing the rough idling in my car. They finally suggested that they change the ECU unit( I am not too sure if that is what its called) This unit cost quite a bomb new. My question is can this ECU unit be repaired? If not can a good used one be used instead. According to my workshop it cannot be done as the computer units are programmed and must be made to suit the car. Being such expensive equipment i am sure Jaguar should provide some form of warranty. I would appreciate some advice from anyone who have experienced this. Thanks. Syed Saed Sounds a bit drastic to start swapping out parts like the ECU - smacks of graspin at straws. Is your workshop an authorised Jaguar dealer, a Jaguar specialist or your local man with the spanners. Where in the world are U. Age car, engine, description of problem, diagnostics already undertaken to resolve problem - i.e. give us some info to work on here.

Syed My car is the XJ8 1998 model. V8 engine.Like i said the car idles rough, like some pistons are out. The whole car shakes and engine sounds very rough. But upon accelerating the power is almost normal. The garage is Sisma Motors, the authorised dealer and workshop for Jaguars in Malaysia.(that's where i am) They have gone through all the checks from compression, pistons, wires, well almost everything and couldn't find out what is wrong. They say their diagnostic computer keeps showing the fault is with the ECU. Well, they have kept the car for three weeks and came with the answers above. They keep no stock of the ECU, so now they want to buy one ( I pay if it solves the problem, but what if it doesn't; I am back to square one) and check whether the fault is really with the ECU. As far as they are concerned there is nothing wrong with the engine. Maybe if i can get some questions to ask them and see what answers they give. Syed have a look at jag-lovers.com a good resource and might give you some answers m Thanks Pottsy, Your dealer has checked the two major worries that can cause rough idle. Nikasil problems and timing chain issues. As it has been with the dealer for weeks we can eliminate shorts in the leads etc. If they have checked poor connections and swapped wires you may be left with just the ECU. Can they not buy one in but only charge you if it fixes it ? > My car is the XJ8 1998 model. V8 engine.Like i said the car idles > rough, like some pistons are out.

From what they say all indications are towards the ECU. Thanks for advice. Moxane |
