Hi folks,
The miggy started playing the bag of hammers tune the other day with the engine management light of the car with spanner through it came on. I read the codes using the pedal trick and got a few that looked like a transmission fault.
Anyway, took it to the garage for the tech 2 test and asked for the codes. It was something to do with the auto box and looking at the list of codes it does point to a tranny fault.
The codes are as follows
P1700 present,
P1625 Present,
P0748 Not Present.
The main dealer said they don't do Auto gearboxes as they never see them these days in modern cars ( cheeky bugger saing miggies are not modern) but they mentioned something to do with a solenoid. The 1700 code as I believe on the site is a service of the gearbox. The car last had a major service at 81k and it was 2.5 years ago and the current milage is now 104k.
If the 1700 code is an oil change that is ok but what are the other two codes for as I can't find them on the site.
Take care and TIA,
Chimpy.

What are the symptoms, is the gearbox stuck in limp home mode i.e 3rd gear and no more than 4000 revs, is it cluncking in to gear, is it holding onto the gears longer than usuall.
First thing to do is to check the fluid level, this will at least rule out the most common problem with autoboxes, there is a perfect guide for this in the maintenance section.
The P1700 code just means that the transmission control module has sent a signal to the engine control module to illuminate the mil lamp on the dash board, once the problem has been rectified and the codes cleared the mil will not be illuminated.
P1625 suggests that the engine control relay is malfunctioning, check for signs of corosion on the pins of the relay. If it looks suspect replace the relay with a known good one.(clutching at straws with this one tho).
P0748 is transmission fluid pressure solenoid-wiring, This could be down to low fluid in the gearbox.
From my own experience i'm pretty sure that i had similar codes when i first bought mine although not the P0748 and mine turned out to be a faulty cam sensor.

Hi buttsy19,
Symptoms are limp home mode if it is in drive but if I put it in 1st, 2nd, 3rd then drive it's ok. A bit of a clunck as it goes through the gears but nothing drastic. Other than that it drives ok, up to 70 and keeps running ok. Starts up first time hot and cold, so nothing really to much other than using a shed load of petrol. I drove 25 miles today and used over 70 miles worth of petrol. Now I know the trip comps are not too accurate but this is way too much petrol for the journey. Also there is a really massive smell of petrol.
The techie at the dealers put the codes out but as soon as he started the car the light came on again.
The engine control relay, that's under the bonnet ?
TIA

Unfortunately, you need the codes from the autobox ecu as well.

First thing to check is the autobox fluid level, being a mig you don't have a dipstick to check the level with. Take your car for a short drive ten minutes or so just to warm up the gearbox oil, then park on level ground and follow the thread in the maintainence section about checking the autobox fluid level, then report your findings back.

Sounds like the selector switch might need cleaning. :-\
