Warranty - Null & Void due to modifications - Page 3

bromers · 03-07-2010, 08:57 AM

My car went into 'slow down' mode on the motorway on my to work, came off at the next junction and it was fine again. Did the same on the way home and engine management light came on.

Drove it to the dealers, workiing fine apart from running a little rough. After 4 weeks they had replaced 2 DME control units, iginition packs, an actuator and a sensor. Car still wouldn't go so a week later, they then find out no compression on two cylinders - 2 pistons have gone and cylinder head needs replacing. Car had been hooked upto Head Office for a few days and then this week they came back and said warranty invalid because it had had an non standard exhaust fitted at some stage (was noted on the last service).

Car's been with them 8 weeks now. Still a slight hope of some goodwill - car's done 28k - full BMW service history (every 12-18 months).

Does anyone think a Milltek backbox (probably on the car for 3 yrs) could have caused all of the above faults ???

No... I don't think it could have caused _any_ of them.

Was it remapped, or could it have had a map that you didn't know about ?

I'm feeling for you Bromers.

Hope it gets sorted. Maybe give Andy Pressland a call at Murketts there isn't much he doesn't know about CSL's and the warranty he will point you in the right direction i'm sure.

BMW are just trying to get out of a big bill if you ask me the backbox would never do any damage to the engine.

But the warranty we all have now does say no madifications so if they dig there heals in there is not much you can do but if you keep at them and i would also tell them you changed the back box as soon as they made you aware it was not the 1 for the CSL

Why don't you talk to milltec and see what they say! And in all the years i've been working on cars i've never had a problem with a modified exhaust causing engine failure unless the monolith breaks up! And one more thing how do bmw sell modified cars and warranty them! as when i was buying mine i found a few dealers selling with warranty and retro fits ; Exhausts,suspension and brakes, Might be worth checking the dealers forecourts for upgraded cars.
P.s Don't yeild! and good luck.

Forgot to add, that they think the piston has hit the spark plug and caused it to break up.

How could that happen ?

The backbox made the pistons more horny, they expanded and ... crack.

The general term for this is called Sci-Fi.
