MERCEDES-BENZ B180 BLUEEFFICIENCY SPRT
Hey,

New to the forum and looking for some help as totally clueless when it comes to cars. Few days ago driving my MERCEDES-BENZ B180 BLUEEFFICIENCY SPRT automatic and the car made some mechanical grinding noises and refused to go into gear giving me an unable to drive without going into gear error code.

Towed to a local Mercedes specialist that I found online as no other car in house so looked for the closest one.

Got a diagnosis back that the flywheel has seized and torn the double clutch to shreds. (Totally clueless with cars so hopefully that makes sense). Been told only way to get the car back on the road is a full flywheel and double clutch replacement and alongside the cost of removing the automatic gearbox, diagnosing it, replacing it, the parts/labour and a gearbox service it will come to just over £2000 (waiting for exact amount).

Now first question I had was does this sound right price wise? Never had a repair like this but seems excessive but I could be wrong.

Secondly I've been told they can acquire the flywheel easily enough but no one around here has a double clutch available and it needs to be ordered in from Germany where there is a 5 week wait for it to be dispatched.

Now being carless for that long with a young family is far from ideal so wondering if there is any recommendations for speeding this process along as in places I can get this double clutch quicker or is that wait an accepted timescale with an issue like this and I'll just have to wait?

Hoping to get some advice to either help or even put my mind at ease that I'm being told the correct thing by the garage.

Hope there is enough information provided but happy to provide further information if needed.

Thanks.
 
I don't know enough about this gearbox to know whether it is a traditional torque converter auto or something else.
Independent of that I am not sure what would cause a flywheel to seize - the flywheel is a big piece of metal spinning - something else must have caused it to suddenly stop - and that is what has shredded the clutch plate material (sounds like it is an automated manual of some sort?).
My concern with it would be making sure that the £2k repair bill definitely fixes the car including the root cause for the flywheel "seizing".
Name the specialist that you have taken it to and see what their reputation is like amongst owners on here.
 
Thanks for the response. You raise A good point that I didn't think to ask in regards to what actually caused it so will discuss that with them Monday.

The place is called Torque Technics and was the closest place I could find that had decent Google reviews.

Any other help appreciated.

Yes it's very common to happen, basically the splines in the flywheel wear and dual clutch unit doesn't spin anymore hence the loss of drive. You are definitely looking around £2k to have it replaced and you gotta take subframe down to remove gearbox, then you gotta swap over dual clutch units, refill with oil and do adaptations. Feel free to pm me if you have any questions
 
Me too , the only thing I an think of is a dual mass flywheel going bad, and thats usually a vibration before total lock up . This car is an automatic , I think we need a bit more info.

Yes it is automatic being dual clutch, but internally its still a manual gearbox. The gear shift forks are actuated hydraulically so it'll still have dual mass flywheel.

Thanks for the responses.

Petrol Pete, any specific information I can provide that can help?

Oleks, appreciate the information. Wanted to PM you but don't have enough posts to do so so I'll ask here.... The roughly 5 week wait for the dual clutch, does that sound about right?

Also are there any other questions I need to ask them prior to the repair? Bit worried that they fix it and the same thing happens again. The car is on 54k miles so didn't expect wear and tear to cause this so not sure if it's just bad luck or a different cause that may occur again.

Thanks again.

Yeah 5 weeks sounds about right, so flywheel, dual clutch cover and dual clutch will need to be replaced. Also its a well known problem with early DCT gearboxes so in most cases you could get a goodwill gesture contribution from MBUK if your dealer has bothered to enquire about it. It also helps if you have full service history.
Hope this helps

The other benefit of getting Mercedes to do it is, they might have a courtesy car available if they need to wait on parts. Might be more expensive, but you will not be off the road.

That's correct, and you're getting 2 years warranty on the repair.
 
Thanks for the advice. I'll call Mercedes first thing Monday and see what they say.
