Picked up the Roomster from UNIT18 having had a replacement clutch fitted.

Alistair noted that the 'kangaroo' effect from 3100k rpm upwards in 3rd is likely down to a faulty/failing injector. So my questions are as follows:-

• Is there any long term damage from running with a faulty injector?
• Replacement/Upgrade to PD130/PD150 injectors - Would my remap need a tweek? or would they simply flow at thte rate the map is 'asking for'?
• Is there a chance one or more may be clogged and is there a 'Try this first' option before replacing the injectors? Injector cleaner or the like?
• What/How can I log some info with VCDS to confirm it is an injector at fault?

Thanks in advance J5

Pd130/150 injectors will need tweaks to the mapping. They flow more so less duration is needed to archive same mg/str of diesel.

Yes I would get the changed immediately mate!! I've witnessed a worst case scenario of a dodgy injector on a landrover freelander, It was fuelling too much and was heating up the piston to a ridiculous temperature, this in turn started to melt the piston and valves. This ****ed the engine and costed an absolute bomb to fix! 

 

Would you risk it for a chocolate biscuit lol?

is it 100% an injector? has the injector loom been checked? my Ibiza had a horrible kangaroo thing going on and replacing the loom in the head made it go away, way less costly than an injector and you can swap it yourself

Unit 18 have a reputation for knowing what they're talking about so there's little point in trying to second-guess them, the loom may well be at fault and is the cheaper option to replace, if the unit injector itself is at fault then simply replace it, no need to change any of the others. Unit injectors don't 'clog' so pluck the 'magic snake oil' idea right out of your head and throw it away. VCDS will not tell you if it's the loom or the injector at fault, only which cylinder is affected.
