Hello all, looking for a bit of advice if possible. I've got a 57 plate Berlingo (Van) 1.6 HDi. Bought it a couple of weeks ago, with the EML on, but drove fine and had no issues with me accelerating hard (and was a good bargaining point) was told it was down to a dudd glow plug by the seller, but once I'd got my diagnostics on it, the fault codes it threw up and a quick search on here pointed toward a fault air doser/throttle body, nothing to do with the glow plugs, replaced with a 2nd hand unit from a breakers, the butterfly valve in mine had no resistence. Replaced, and sure enough the EML went out, I also cleared the codes stored. However accelerating down a slip road to get on the M6 the other day (first proper run since replacing the throttle body) and the EML came back on and it went into limp mode, pulled over switched off and back on and although the EML stopped on it wasn't in limp mode. Got home checked the codes and it came up with P1351 (Glow plug) and P0121 (Throttle Position Sensor), it also had a stored code of P0234 Turbocharger overboost. I'm thinking it's another dudd air doser/throttle body, but I'm looking for some reassurance that my thinking is right that the fault code in relation to the Overboosting is down to a faulty TPS in the Throttle Body/Doser before I go into Citroen and order a brand new one at the Cost of around £165.00 trade :brickwall:
Or is there something else that could be causing this, turbo was replaced around £2k ago, along with all relevant feed pipes etc etc, suffered the usual fate of being starved of oil. Love the van, easily sorted the odd little issues it had when I got it, but this one is one I could do with sorting as I rely on it for my business, and it's a bit brown trouser if your trying to get up to speed to join traffic and it decides to cut the power!
Grateful of any help in this matter, the diagnostics I used wasn't Lexia, but Lexia is on order!!
