It's the 92hp 1.4 16V Hdi engine. The totalcost of the job is over £400 as the injector costs over £200. It has just been completed and the problem has clearly been solved for the time being. However there are two original injectors still there and I hope these will prove to be more durable otherwise I will be faced with a further large bill. The Citroen dealer is talking to Citroen UK to see if they are prepared to make a concession over the price of the work. If they don't I'll deal with Citreon UK direct and if this is a known problem it would help my case.
