Hi. I have an issue with my 2007 CRTD CDX + , 2.2 l, Diesel Automatic. (127.000 m)I have browsed through the threads but can't seem to find a matching one.

Recently the car started to shudder when engine first started and even stalled twice when put into reverse. However after turning ignition off and back on again all was fine.
The second issue was when first driving off , there was only very little acceleration for the first 3 seconds and then it would suddenly kick in. The engine revs normal in Neutral.
The car drives and accelerates without issues after the first three seconds.

As the shudder problem was getting worse I took it to my local independent garage and after some tests it turned out that the DPF was faulty and was reaching extreme temperatures after only a short drive .
DPF has been replaced and the shudder / stalling issue seems to be resolved but the acceleration issue remains without obvious fault .


Garage spoke to local Hyundai dealer who unfortunately weren't much help.

Has anyone experienced this issue ?!

Hi Tripplec

Thanks for your note, not sure if I understand , what do you refer to in terms of codes?

Many thanks

The mechanic or dealer need to scan for codes. It will identify faulty areas. Without any codes its all guess work. You need to see an auto engine specialist. Could also be from some lack of service a subsystem has shutdown because of it.

NOTE: We don't have diesel SF's in North America

Well, spoken to the garage and the car does not show any fault codes at all since DPF replaced, and carried out all the tests they can think off so complete guess work and keen to find out if anyone has experienced the same issue.

Any ideas would be most appreciated !!!!

Dirty injectors? Vacuum leak? Slightly low fuel pressure initially? Contaminated fuel? A vacuum leak might set a fault code but the others probably wouldn't.

As Tripplec said, we don't have diesels in North America so these are just guesses, but these problems might be seen in a gasoline engine and the symptoms may be similar in a diesel.

Short drives creates problems with vehicles over time. A good diesel mechanic should be able to figure it out. As DSHORNET says in his post. A lot of areas could be assess. Listening and paying attention to the symptoms and sounds of the engine may reveal something. But a skilled mechanic is needed to narrow it down.
