Issue After Recall And Timing Belt

[bluecraigy]

car has 133k on clock and had the timing belt and waterpump changed along with inverter recall. Bought up a couple of issues when doing the general check like a blowing exhaust (replaced with custom made stainless steel from Tony Banks in Leeds) height sensor failure ( replaced linkage with one made by SGS engineering in Leeds) and ARB bushes can wait till MOT.

The car was running ok but down on fuel consumption quite dramatically and now has developed an intermittent clattering on start up sometimes up to 1 in 5 starts. Anyone any suggestions already replace spark plugs also?? Main stealer said it was exhaust blow causing it and charged me £54 for 10 minute look wash and vac and nice coffee!! and it definitely is not that.

Others have had a similar issue with economy after the recall work. There is a post on here somewhere about a reset process that may help - do a search.

Maybe it is possible the timing belt was not "timed" correctly upon replacement, just one notch out would make a big difference to the efficiency of the engine, and the clatter dare I say could even be a bit of valve/piston contact in extremis.

[Boxbrownie]

Another point, after replacement of the timing belt maybe the VVT operation has been disturbed?

IT is very intermittent and has no rational as to when it decides to do the clatter but after a few seconds its fine, and overall the car is running with no issues to point to anything further

Well if only on immediate start-up (especially when very cold) it most likely is one of the hydraulic lifters a bit sluggish filling with oil pressure.

If you aren't happy with the repair take it back to the dealer that did the work and express your concerns, if all was OK before the work why is it not now s the question you need to ask.

Take it back to the dealer that did the work if you believe it is that.
