I have a Renault Espace 3.0cdi Bj. 2005, alongside his main problem to be a bad design, among others constantly dirty valves of the injection pump and a filthy Abgasrueckfuehrventil (AGR) has to do. My Grease Monkey has me highly placed the System Cleaner to his heart after he had changed the EGR. I initially followed his advice just for 2 tank fillings and got the EGR error message after a short operation without the addition again. So I added the extra and get back since then (since autumn 2010) no problems in the mentioned type. Previously I thought that these additions are only esoteric stuff. Now I think that it certainly has a cleansing effect on valves etc. In the vast majority of vehicles to the effect probably can not see as directly as the Espace 3.0cdi. For owners of such cars this additive, however, is the pure Fluessiggold.
Have fun driving
SUPPLEMENTARY 03/12/2014: I cant this stuff since autumn 2010, now almost in every tankful. Until now there were no more problems with dirty valves of high-pressure pump or the EGR. Toi Toi Toi. One may wonder whether it really worth it ... well, the fixed price for cleaning the high pressure pump was my last time at 800, -. These are system cleaners in about 90 bottles. With a bottle per tank brings me about 76500km far. For me, fits the Oh, if someone has the above Espace and someone needs that can repair the without spending 5000 -. To take (such as the Renault workshops for the exchange of high-pressure pump) -> HAS Antriebstechnik in Winterberg / Sauerland.
