In answer to the question, I have a Maserati 4200 and now I can imagine you all thinking well what do you expect ? You can't compare it with that. No you can't and there's not much that you can compare it with. However I also drive my wife's 1.9 Polo diesel and a Vauxhall Vivaro van plus the odd motorcycle. So I am very much aware that it's not and never will be a rocket ship. Reading Black abbots description of his cars performance that's how I expected mine to be but it isn't. There can't be much wrong with it though as it starts easily, idles reasonably smoothly, is quiet and will return 42 mpg. Am I right in thinking that the Vanos control the oil supply to the variable valve timing gear? If this is correct could an internal oil leak cause the valve timing to lag a little. This is just a guess and is probably wrong.
Hi, the vanos is the variable valve timing, the oil to them is supplied by vanos solenoids which can get blocked by debris/crud-people have had success removing them & cleaning in white spirit or petrol before reinstalling.
Any leaks will be visible on the outside rather than internally, this is usually just a damaged o ring
