Hi Dave,
Thanks for your advice - really was sound !! after sleeping on it and speaking to a few independent BMW dealers who have advised that this clicking from the inlet manifold / lifters is not a characteristic issue. And thus could take some time to diagnose and may not be a cheap fix. Will be walking and collecting my deposit.
Gutted! Eager to replace my 1 series!!
Any ideas for outlets other than autotrader for used 1 series petrol good condition low miles. Budget 8-10 k (lower end for private bargain. Higher for trade premium & warranty)
