(More) Selespeed Advice!
I have a 2002 147 Selespeed with around 86k (Mainly driven by a lady so a very light touch!) on it which has been fine up until recently when we have had the occasional jumping out of gear between 2-3 into N. It was very occasional so wasn't really a problem. But like all these things it gets worse.
My local specialists (Day & Whites - Brands Hatch) have been working hard to trace and rectify and so far have done the following:
Run extensive diagnostics which have given no codes and all the functions are working as they should. Everything was reset and lasted about a week before jumping out into N again usually between 2-3
Changed the Battery for a pretty substantial unit and ran diagnostics again all seemed to be in order (Note: Battery had shown a lower than expected voltage so I was optimistic)
Happened again within a couple of days. More testing and this time a crank sensor, speed sensor and the selespeed wiring loom has changed as they had all shown some form of fault. Diagnostics run and no codes with everything working fine. Also road tested by them over around 50 miles or so - Again I was optimistic.
This morning it was fine until a little light traffic which meant 1 to N and so on nothing worth going into 2nd for. Then when pulling away into clear air it went 1 -2 and then to N. Recovered by tapping lever backwards and it engages 5 then tap back to 3rd and we carry on without stopping. Howvere it got worse and we had to stop a couple of times to allow us to find N and set off again. I could then provoke it by backing off the throttle slightly at the point that it would normally change to 3 and sure enough it would go to N. I decided to limp back to D&W without turning the engine off but by the time I had left the traffic behind and run back down the M20 it had stopped failing! I left it running and D&W connected up their kit and went off for about 20mins and guess what it behaved just fine!! They are going to take it into traffic later today with the Diagnostic kit connected to see if they can replicate it and we will go from there.
Obviously this is all adding up now so I would appreciate informed opinion as to whether this may be a dreaded actuator fault (Auto Lusso think it is) which in all reality would consign it to the scrap yard or something else. Accumulator? Gear lever?
Wiring connections have been cleaned so pretty sure it is not just a loose connection
By the way this fault happens whether in manual or city mode.
The pump sounds fine and starts up without fail every morning and I can hear it priming occasionally.
There has been a v. small leak of Tutella - just a few drops perhaps and certainly the oil is kept topped up.
So what does the collective think? I have read plenty of the threads on hear but in all honesty they all point to different things so, based on the experiences I have detailed, I would appreciate comments.
Really don't wan't to scrap it if I can help it....
