Locking Wheel Bolt

[C220CDI]

Hello

Had a puncture yesterday. Whilst opening the bolts, I slipped the locking wheel bolt and broke it. Its an oem Merc type.

Spoke to Mercedes, and they think the code for the nut is in the service booklet. Had a check, and of course it aint!

Any ideas where I can find out, and purchase the right one ?

Cheers

What year/model is ur car ? - if i.e. a W203 then call MB Cus Services with your Chassis/VIN details and they will be able to identify which lock nut key it is from their records (thats if it is the OEM bolts/lock nuts from factory...).

Alternatively, Stealers have a master set of i.e. 20 odd plus lock nut key cobinations and one of them will fit ur lock nut and u can identify it from that.

The above will only apply if ur car has the OEM MB Lock Nuts...

Yep, as flash has said - pop down to your MB dealer and explain the problem. They should have a master set which will have a full set of MB wheel bolt keys.

If the car is immobile, maybe mobilo etc can help?

Good luck

Same thing happened to me a short while ago.

The stealers tried almost all of the master set until they found which one fitted and then sold me a replacement for £20.

Count yourself lucky. Guy I work with has a Volvo equipped with lockers with a great many variations and that resist most of the usual methods. Dealer welded some kind of rod onto the bolt heads and backed them out using that.

Not cheap.

Thank you for the advise.

Mechanic removed the locking bolt with a chisel and hammer, so got the spare on. Took the car to Mercedes in Reading. They removed the rest of the locking bolts and replaced them with regular bolts.

Now the surprise, they did'nt even charge me!!!

Since you ahve regular bolts on now, will you replace them with locking nuts again?

I think Alloy wheel theft isn't as much a common crime as it used to be. It's been ages sicne I seen a car sitting on bricks.

Greenoaks have had alot of complaints and alot of their customers are switching over to Hughes apparently - hence why u may not have got charged or they had some old corroded bolts lying around removed from a second hand car that they had to remove and replace with new shiney ones or something...

PS. Next time ur at Reading tell Richard Bernard (Servicing Manager) that I said he is a Pr*ck...

Exactly. When i snapped my locking-bolt key (after a kwick fit fiasco), I just replaced all the locking bolts with ordinary ones. Locking ones seemed like too must hassle to me.

Company next to where I work import the occasional car or two, one came in with locking wheel bolts and no key. Easilly removed with long shank 18mm socket hammered on. Undo a couple of turns then remove the socket. When I saw it done, I thought why have locking wheel bolts, they are soooooo easily removed

It does make u wonder then what is the use off locking bolts but thing is if u have very nice alloys then using force with other tools other than the actual designated key could potentailly damage the alloys' nut housing area and lead to corrision as well as marks on the wheel. MB alloys are already sensitive enough as it is to corrosion.

I remember some time ago Shude had a similar problem with wheel bolts. IIRC he went to a local engineering company for assistance.

The socket does not touch the alloys, it is merely forced over the locking bolt undone and removed. No damage to the wheels, Jeeze you can't sell damaged goods

just had to replace my locking nut, so i went down to MB, they took the reg and model and replaced the bolt in 5 mins.. cost £26. i will not leave it in the wheel next time

Having seen two locking nuts removed off my c230k in under 10 minutes I doubt they have any real security. As said, chisel, hammer and socket. The locking nuts are not worth it unless the wheels are really very expensive and in good nick.

just had this problem.. MB garage cant do anything about it unless i book it in. Its stuck so bad the key wont lodge. I've found a garage that apparently does these in 10 mins for a tenner. that being said, im now 4 bolts short, where can i get replacements because mb dealer told me they dont stock them anymore?

Have heard too many people who broke the locking bolts when trying to get a wheel off. Bad design means that the hollow bit fills with dirt so that when you apply the wheel wrench it doesn't fit properly.
My advice to anyone is either buy a new set and swap the locking ones for non-locking ones or go to a breaker and get 4 non locking bolts there.
