Hello there looking for some advice had my 220 d lexus for about 2 years and in the past fortnight after refuelling £30 worth of shell diesel car run like a bag of spanners. My garage advised me to fill up with shell v power which cured the problem and was advised this would sort out. Last night put £40 shell v power drove the car 1 mile from garage and everything ok . Today car going worse than before had to call out rac and they reckon it's a fuel pressure problem. No lights or fault codes on dashboard any help would be appreciated thanks Derek
