Mitsubishi L200 B40 2.5 Di-d

We have a 2012 L200 B40 2.5 DI-D 37000 miles. It has a missfire on idle and is noticeable up to about 2200 rpm. It feels like a definite missfire on one cylinder. There are no stored codes,EML off, and no useful live data on Snap on Solus. Vehicle performs very well and missfire not detectable when ...

Re: Mercedes 500 SL 1990

Thanks for your reply. I don't have a pressure transducer but still have a timing light gathering dust on the shelf. Checked with this and Ignition timing showed up fine so I was reasonably confident that the spark was somewhere near. It is now fixed, turned out to be a faulty ignition coil. I had c...

Re: Freelander 2 slight hesitation at 2000rpm

Yes I agree entirely. There is a great deal of useful information on the forum and some informative clips on youtube. It would be great to have the time to attend courses but unfortunately my role as (manager/mechanic/sales person etc.etc.) does not allow.

Mercedes 500 SL 1990

WE have a Mercedes 500 sl V8, 1990 which refuses to start. We have all the ingredients present but will not attempt to start. It's a LHD on German plates and not checked it's build date yet. Engine cranks normally. Good fuel pressure. New Spark plugs. Crank sensor resistance normal. Good spark from ...

Re: Freelander 2 slight hesitation at 2000rpm

Apologies for the late update but we waited for the customer to use the vehicle for some time before we could safely say that we have fixed the problem We eventually fixed this using "gut feeling" and not electronic diagnosis. The fault seemed to occur with reasonable consistency and we linked this ...

Re: Nissan X Trail 2.2 dci won't idle when cold

The problem is now resolved. New timing chains and gears fitted and all is well. When we removed the upper chain cover, the timing was visibly out due to worn chains. In future ,the quickest diagnosis will be to disconnect cam sensor, and if it runs well, inspect the timing chain. Thanks to everyone...

Re: Nissan X Trail 2.2 dci won't idle when cold

Thanks again for your reply. The Crank signal voltage was corrected simply by removing the Cam sensor connection. In doing so it corrected the voltage and also allowed the engine to idle properly. Out of interest, we disconnected the crank sensor and scoped the cam signal assuming that we would get ...

Re: Nissan X Trail 2.2 dci won't idle when cold

Thanks STC for your detailed reply. I will have to study it more as I am still unsure where to start counting teeth etc. and cam/crank signal relationship. I have captured the waveform for the 3 wires on the crank sensor. This was taken with cam disconnected which allowed it to idle perfectly giving...

Re: Nissan X Trail 2.2 dci won't idle when cold

I have managed to get a reasonable waveform from Ign. on through to engine stopping. Advice on interpreting this will be appreciated

Re: Freelander 2 slight hesitation at 2000rpm

Thanks Andrew, any information is welcome. It is difficult to reach but when disconnected the variable vane control arm is very loose and I can't detect any resistance. Based on this , I have to be satisfied that the turbo is OK. The car is back with the owner for now. Next step is to scope the thro...
