Yes I will have to take the unit out, I was hoping that someone may have had a similar problem and could help pinpoint the likely cause. When the display is working it is very clear and backlight brightness can be altered from the control on the steering column. So bulbs seem OK. Bad contact...

My 2001 P38a HEVAC display screen is having an off day. It shows a black screen when the car is started and sometimes comes back on after the car is driven a few miles. At other times it responds to tapping the screen. The screen seems to have a small amount of movement and pressing the edge...

Been away and having difficulty with this new site! Thanks for the advice so far. Car is going in for some diagnostics next week so your advice may help to resolve the issue. The car is 2001 and it does have a EGR valve. Had a new in tank pump fitted about a year ago. The car runs OK when...

My P38 Diesel Auto stalls from cold but settles down when temperature reaches normal running. However, it does stall on occasions at road junctions etc. I have a hot start fitted and removed this to check for any changes but the problem still persists. My car is used mainly for short...

Getting rid of the car has always been an option .. but it is a P38 so problems will always appear!

Got a new viscose fan fitted and no leaks from the old fan. Its not brake fluid and there are no leaks from the AC pump. The Steering damper is probably the most likely candidate for the leak. Will check that next. Any other ideas?

Yeah OK one '0' too many should have typed 850 RPM! .. always has been around the 900 mark even before fitting the hot start. .. Wonder if the engine has been chipped? Suggestion that a heater plug might be down is a puzzle as the engine fires up first turn of the key ticks over at 900 to...

I had a Hot start Fix with the timer fitted about 8 months ago which cured the hot start problem. However I have a cold start issue that has developed recently. The car starts first time but after the hot start Fix timer period of about 30 seconds ends the engine begins to miss and when the...

I have a P38A DHSE and have a oil leak which leaves a small patch on the ground overnight. It is a clear oil like caster oil .. Not diesel, Not engine Not power steering or gearbox oil. The source is difficult to locate it is lightly smeared on the flexible hose from the gearbox and is also on...

Thanks for the comments guys. Must admit that my gut feeling is that there is a problem at the rear end of the vehicle. The strange thing is that it is always both sides of the rear end that drop. Some days the suspension does not drop and at other times I can ride round the block and on...

Datatek and wammers Thanks for your comments. I had thought that the source of the leak would be in the rear end but the garage has checked this area and could find nothing wrong. If the rear end drops then pumping the vehicle up to the maximum will hold the suspension overnight without loss...

I have been experiencing problems with the air suspension system on my 2001 P38. Rear end can unpredictably slowly deflate and very slow to recover so air pump replaced. The air bags now inflate quickly and can remain under pressure. But the rear end still unpredictably deflates. The valve...

I have a solar panel to mount in the P38 Boot. I plan to use the lighter socket which will have to be converted to be permanently live. I have read the various threads on this same subject which recommend the feed direct from the battery (+) terminal or connect to a Becm (+) screw terminal...

I should mention that the low range gears work fine with both the petrol and the diesel version Transmission Controllers. Its the normal range thats not working properly. Would a fault with the engine ECU cause the problems I'm getting? The engine starts and runs fine and there are no faults...

Thanks for your reply Datatek. I can't understand why the petrol version transmission controller works fine though obviously the speed controls mapped into the controller are not suited to the diesel version. I suppose it is possible that I have got two faulty Diesel controllers which is...

I'm having trouble with the gear change on my 2001 DHSE automatic. The gears won't change up. At about 3500 RPM the gear reluctantly changes up and the revs drop off but after the throttle is pressed the revs shoot up again. The gearbox is obviously running in low gear. Moving the gear lever...

The fault showing on the display reads GEARBOX FAULT. No doubt this is due to the petrol controller being installed instead of the diesel unit. Ive been told by a main dealer garage that if you do'nt fit the matched unit for the vehicle it could mess up the solenoids and create all sorts of...

Thanks for the responses. I had the computer on the car which showed no faults recorded! The unit now on the car is for a petrol engine so will give odd results but does get me mobile in the short term while I look for a diesel version replacement. Looking over the net there are a number...

My 2001 P38 diesel would'nt change gear and was only capable of 35MPH with the engine revving it's socks off. The Transmission Controller has failed. Trying to locate one to suit the vehicle it seems the system was changed in 1999 so earlier model units won't work properly. I've fitted a...

Thanks for the replies. I have checked the fan .. this is OK. If the Thermostat has failed I thought they failed closed? Could be opening too early and staying open. Anyway this is being changed. Any thoughts on the engine amber light and the fault showing No 4 injector lead. Could be...
