There's a lot to be said for buying genuine parts.
Yeah, though the genuine part is ridiculously expensive, and if I ask my dealer to post it, they aren't the quickest. So took a punt on egay, foolishly. And now I haven't got a car to get me to Ipswich this week , though apparently I still have to go
I'd lend you the Proper Car, but you'll be limited to 40mph and about 15mpg
I sympathise re the dealer though... The parts manager at my nearest is a total bell end*, his staff spot on but he's obviously chasing their commission.
*He actually threatened to refuse to sell me parts that aren't listed against my chassis number when I asked him about coding and went as far as to say that servicing wouldn't touch the car even after I offered to pay them to inspect everything to confirm that it was all genuine and correct
Fortunately I drive past a much more useful dealer on my commute.
