Quick question. Are the rear bags on the p38's the same across the model range? 2.5 diesel and v8 petrol the same? Finally got the suspension moving using the EAS unlock software this evening and the rear right is very sluggish on rising. there's an auction on ebay at the minute for rear airbags with no reserve and a very low starting price so I'm guessing i might throw on a few euro on it and get them cheap. Only thing is that they're listed as 4.0, 4.6 v8 and I only have the diesel.
