Personally I would not touch the Q-Drive/Ocap POS.
On my old 205 GTi the drop links were shot within 2k and 3 years - all boots were scrap and I needed the car MOT'd that week. Q-Drive they were; I was due to sell the car that week, and the drop links were the difference between the MOT and not getting one. Oddly enough the car stopped knocking as well.
On the Clio the ECP sourced TRE has lasted 23 months and 18k, it failed it's MOT this time around; Pretty shite when some of my cars had gone onto 6 figures with the original items an still with zero play present. I am hoping the Lemforder item lasts longer.
Don't get me wrong, I don't like throwing cash around but I hate doing the same job twice and spending more overall! In this case the PO changed the TRE going by receipts and MOTs, but still; it shouldn't have failed this soon (it's passed 2 MOTs under my ownership).
For the people who find ECP stuff how many miles have you covered in the car; is it a daily?
