SZL Module Reset (post clutch change) Solved

(’07 MINI Cooper w/ DSC)


I wanted to pass this on to everyone because I was getting bad information from the dealer and a local Indy shop, and the Bentley service manual is incomplete when it comes to the instructions for replacing your clutch.


I recently replaced the clutch in the 2007 MINI Cooper. The Bentley service manual (310-9) tells you to disconnect the steering universal joint by removing the pinch bolt. This is needed since you (in the Bentley version) lower the steering rack down with the sub-frame. Well that's all fine and good, but it fails to tell you that you must retain the relationship (zero degrees) between the steering rack input shaft and the steering column (the steering wheel SZL module).


When you finish installing the clutch, the manual tells you to have a wheel alignment and steering angle reset performed, so I was off to the dealer.
When I took the car in, the dealer completed the alignment, but they said when they reset the steering angle sensor that the fault kept coming back. They quoted $1000 to replace the SZL module. I was skeptical, so I called a local Indy shops. They wanted $500 to replace the SZL module. I was still skeptical since I didn’t understand how disconnecting the steering linkage in the footwell caused an electronic component to fail when the battery was disconnected.


So, I did some reading on this forum and I came up with my own plan. I purchased a Foxwell NT510 scanner on Amazon. It's the same one ECS Tuning sells under the Schwaben name, but the Amazon version is $30 bucks cheaper. After registering and updating the scanner, I hooked it to the MINI. It auto recognized the car, VIN etc. I started the scan. I had faults in six different modules, Steering, DSC, Footwell, turn signals, wipers, air conditioning, etc. All of these faults were related to the fact that after I had disconnected the steering universal joint and then moved the tie rods around to disconnect other suspension components. When I put everything back together, the SZL was not centered (zero degrees) with the steering rack input shaft.


With the wheel alignment complete, car in the garage w/ the front wheels straight, and lots of warning lights on the dash, I connected the scanner. I pulled up live data and selected steering wheel angle sensor. The scanner showed -356 degrees. So, I removed the pinch bolt, and disconnected the u-joint. While watching the scanner, I turned the wheel and watched until the scanner showed 0.0 degrees. I reconnected the u-joint and reset the steering angle sensor. It worked perfectly!!! After that was complete, I proceeded to clear the faults in the other modules. All the lights on the dash went away and did not return; wipers quilt coming on whenever they liked, and the turn signal cancellation problem went away. So my $179.00 investment in the scanner saved me the $1000.00 charge at the dealer for a part I didn't need.


I’m still amazed that a factory trained service technician couldn’t have figured this out. My next step it go contact the Bentley service manual folks. Their instruction for changing a clutch need work.


Happy Motoring!

i suspect that the dealership wanted to change your SZL module knowing that it would have to be zeroed in. The profit is there and they could have gotten away with it. The dealer has done clutch jobs before so they know the procedure plus they have internal technical directions of what has to be done which would include zeroing out the angle sensor. Good for your persistence, shame on dealer and thanks for sharing.

Great information, thanks for posting! Moved to the How To forum because this applies across all the Gen2s.

Same experience, replaced the clutch and all the lights came up for DCS and brakes, indicators not reseting and wipers doing their own thing. Now I knew this was a SZL column switch angle sensor problem because on this Gen 2 last year I changed the SZL and had it 'coded and angle reset' at dealership. Went to them this morning and they suggested a new SZl. How could sitting on axle stands and having the ECU disconnected for 5 days blow up the steering control unit? Paid them their 30 minute fee and started reading like mad and MKOV just saved my day!!! Kudos and genius work.
Just back from the car now and used INPA to watch the angle sensor go from 358 degrees to zero, one turn of the wheel then reconnected the pinch bolt/rack. Reset the angle using INPA and cleared codes... everything back to normal, no lights, signals reset again and I am very happy.
Thing that gets me is dealers must do this clutch every week/day so why the big scratch of the head and it is broken attitude? They did not even go as far as to give me a replacement price or begin to fleece me. Very odd. Thanks again for your post! I used Haynes and no mention in there either and when the column is disconnected that steering wheel spins at the slightest touch, I though I had it centred but was a whole turn out...

Excellent question; when I asked my local service manager how a guy with a $159.00 scanner can figure this out when a factory-trained service technician can't, she said that the dealer mechanic risks breaking something inside when they turn the wheel with it disconnected, so they don't attempt this type of repair ... they would rather charge you $1000.00 for a part you don't need. My brother suggested dealer mechanics aren't trained to troubleshoot ... they scan computers, look for faults, and change the associated component.

While I was waiting, the 'technician' took the motor out for a test drive, away for more than 15 minutes, bet he had a lovely time and not sure exactly what that was for. A cigarette no doubt.
Anyway, have emailed the bloke I was dealing with to let him know the solution and to prove that I was the cause of the fault (and that they are numpties). Don't suppose he is going to refund my 45 euros or the three hours I sat waiting and arguing. Takes a fair bit of force to break the clock spring cable, I spun mine a few times to get what I thought was half way before reassembly, there was my problem :-)
Thank goodness for the interwebs, forums and your genius.
