Problems with BCU
 

Hello everyone.

I hope this post is in the right place.
I have a MG ZTT diesel 130 face-lift model. VO 54 MKP

Last year, I noticed the cruise wasn't working. Checked fuses etc but couldn't see anything amiss but as I don't use it much I wasn't too bothered. Over the winter, I noticed that the brake lights stayed on for a couple of minutes when I started first thing in the morning - at the end of the street the lights behaved themselves. I had to undergo chemo/RT and then surgery in February 2020. On Friday 20th March, the day lockdown was announced, I noticed that the front fog lights were on continuously. I couldn't do anything other than disconnect the battery over the weekend. My usual garage (a former BL/Rover/MG dealer in Cardiff) shut for a couple of weeks but when he re-opened, he said I needed a body control unit which he obtained and fitted. The fog lights were sorted... until a neighbour said 'your front fogs are on'. He then replaced the BCU again together with another control unit from another MG. This was successful for 3 days until the problem recurred. He said I needed a T4 computer to reset the units. The only problem is - he seems to have given up. He says he will collect the car but doesn't.
It hasn't a problem as I've been shielding since my cancer treatment, but will need to go back to work soon.
Now the restrictions have eased in Wales, I can now travel.
Do you know anyone expert in solving this problem

Thanks in advance. Rob

Try getting hold of Wynn Fellowes in Swansea, has a T4, said to be on Facebook, also know as eurorover.

or Mark at MJN Motors in Bristol. http://www.mjnmotors.com

The fog lights are not anything to do with the body control unit, I don't know what made the garage think that :shrug:

The fog lights are controlled by the light switch module ;)

If you got a used replacement or borrow one to try and the fogs go out then that's the problem ;)

Thanks for the message. I have now been able to travel to Bristol to see Mark at mjn. As you say, the lights are controlled by the light switch module, which Mark replaced from a donor car. Lights working perfectly now that everything has been re-set using T4. Cruise control also rectified - T4 showed 'clutch depressed'. New clutch fitted in France 3 years ago and they must affected the sensor. Mark adjusted the sensor as well. So all good. Thanks for your comments and recommendations.

Thanks for your message. I have now been able to travel to Bristol to see Mark at mjn. He has done a fantastic job at a great price. Supplied a replacement light unit and re-set the cruise.

Thanks Roberto for posting the successful resolution to your problem and for your endorsement of Mark at MJN, Bristol. He's certainly in a different league to your former MG Rover main dealer in Cardiff who we would all expect to have better knowledge of the 75/ZT! :o
