Selespeed dropping out of gear
I've had my 147 Selespeed for coming up on two years and it has developed a fault (which I've had in the past) of dropping out of gear to N and then refusing to select gear, this can be rectified by turning the engine off, restarting, waiting for checks and away you go. This is not loved by the ever "patient" drivers in the part of London I live in ;-) The problem seems to occur from cold and be more pronounced when the weather is colder. I should also add that I only tend to drive the car on weekends so it will be sat on the road getting beaten up by the weather for 4-5 days in a row before it gets a turn over (not that it is ever that bad in London).
It has been fixed in the past by adding more Tutela CS Speed and at the start of August I had a Firela look further into the issue and they took the actuator apart and replaced some leaking seals in the unit (and I thought the problem was fixed).
The pump is priming fine when the door opens for around 10 secs and when I turn the engine on I can select 1, 2 and R however I have noticed that the gear changes 1 through 3 are clunkier than usual. When it failed on me last night in a parking lot, I was in City and it went from 2nd to 1st and then there was a noticeable judder in first and when I was on a ramp awaiting other cars to depart the car park it dropped into N and I had to do the turn it off/turn it on routine.
I've ordered an ELM cable and will use MES to read-off any error codes that I may get (I'll update accordingly, I also have another bottle of CS speed on it's way to top up to check if it's leaking again, it looked fine level wise when I check on Saturday, but as the oil is quite clear, it's a bit hard to judge on the plastic dip stick). But has anyone got any suggestions what may be causing the issue based on what I've mentioned above?
I'd appreciate any feedback.
