When driving abroad (I'm from UK) last Thursday, my car (S500 LWB from
1996, W140) broke down seconds after taking off from a parking lot.
The engine just seemed to lock up. Didn't crank when trying to
restart, all warning lights on.
The vehicle got towed away to a local Merc garage. Called me to say
that the timing chain had broken and the engine locked up as a result.
Quoted me over 33,000 euros (!) to fix by putting a new engine in.
Question: while I understand that valves could have been damaged as a
result of the timing chain breaking, is it likely that this has put
the entire engine beyond repair - especially since I had only just
taken off again?
33K euro is clearly well beyond the value of this vehicle. Are there
any other options I should consider or do I write the vehicle off?
Also, I thought this was not supposed to happen with these vehicles? I
asked an engineer about a year ago whether or not I had to have the
timing chain replaced (then 93K miles, now 100K exactly), he said no,
they did never need replacing...
