Peugeot 308 Turbo

9 engine variants, all with a brand-new turbo: how to find the right one for the 308

All turbos in this collection are brand-new parts only — no reconditioned units, nothing to return. This direct-sale approach applies to all 9 engine variants listed, whether diesel (1.5 BlueHDi, 1.6 HDi/BlueHDi or 2.0 BlueHDi) or petrol (THP and PureTech). Rebuilding your own turbo is not offered here: it can make sense for a rare or hard-to-source part, but the availability of new units makes that approach less relevant for the 308, whose manufacturer references are still well covered.

Finding the correct reference using the engine code

The 308 spans several generations and a wide range of engine codes: the 1.5 BlueHDi covers codes DV5RCF, DV5RD and DV5RE; the 1.6 HDi/BlueHDi 100 covers codes BHY and DV6FD; the 1.6 BlueHDi 120 / HDi 120 / 2.0 BlueHDi 150 group covers codes 9HC, 9HD, BHX, BHZ and DV6FC. On the petrol side, the 1.6 THP comes in several power outputs with distinct codes: EP6CDT and EP6DT for the 150 hp first version, 5GY (EP6FDTM) and 5GZ (EP6FDT) for the 150/156/163/165 hp versions, EP6CDTX for the 1.6 GTi 200. The PureTech 110/130 carry codes HNP, HNS, HNV, HNY and HNZ, and the 1.2 THP 130/131 carries code EB2DTS. The same quoted power output can correspond to different turbo references depending on the year or generation: the engine code stamped on the block is the only reliable way to identify the correct part.

Symptoms and root causes to address before replacement

On the 308's diesel engines, variable-geometry turbos are prone to fouling of the distributor vanes, typically caused by degraded oil or a clogged EGR/DPF circuit. On THP and PureTech engines, lubrication failure at start-up and air leaks on the intake hoses are common causes of CHRA failure. Whistling, persistent blue smoke or the engine dropping into limp mode are the usual warning signs. Fitting a new turbo without identifying and fixing the underlying cause is never enough: the service life of the part depends directly on the condition of the oil circuit and the intake system.
