Bruce, Vauxhall/Opel Meriva 1.3 CDTi

Hi Jerome, I purchased a V-CR unit for my Opel Meriva 1.3CDTI direct from you in early April, I have now had the chance to run it for a month and over 1000 miles. In a word "Superb". The little JTD engine has always been flexible and willing but a little down on power, especially on hills. This has now all changed, there is a lot more power at lower revs, the acceleration is better and it's quieter. I have not had a chance to accurately check the consumption but it looks as though I am using less diesel than before.

So a very happy customer.

Kind Regards

Murray, Toyota Hilux 3.0 D-4D 171BH
