Just seen this thread, can't believe this guy is still in business. Took my mkiv n/a to him about 3 yrs ago to have the cooling system checked because the heater wasn't working. Picked it up the next day & it was a different car, misfiring, wouldn't accelerate + heater still didn't work. He said it was dampness & it would be fine after a good run once it dried out? He'd flushed the cooling system out and completely soaked the engine in the process.
After a week it was the same, took it back to my usual garage (Woodcock Hill, Surrey) who found that the front cat was completely knackered and the plugs were sitting in water, took them quite a few hrs to put it right.
Stay well away from this guy... :thumbdown
