There have been general reports about Dicor vehicles
Yahoo! Groups
Yahoo! Groups

then there are steeroid and tsk1979's safaris. Though they are both running fine now, the issues they faced are not something others face.

cost effectiveness = you spend 50k extra to buy, and a few extra thousands to maintain an indigo dicor, 30k for an indica dicor and you dont get any substantial benefits over a TCIC indica, like mine. While the TC/TCICs were a substantial improvement over the NA versions, and the price difference was not at much - 15k between the NA and the TC, and 10K between the TC and the TCIC.This would put the Dicor squarely in the Diminishing returns category IMO

Maybe I had too high expectations of them.

Greenhorn the thread is a little misleading.
Let me clarify doubt one
1. The Indigo Dicor.
Now why would you pay 50K extra for the indigo DICOR?
The answer is simple. The engine is much better than TDI. How? 2BHP more? Well no. The TDI engines peak capability is around 75BHP. AT 70 horses, its actually ouputting the best it can give.
On the other hand the 1.4 DICOR easily manages 90 horses without breaking a sweat. The problem is gearbox. With 90bhp at same rpm, you would need a beefier gearbox, which would push costs up by 20-30K more, therefore the engine is running detuned. So nothing wrong with engine Per se.
Its a problem on product intergration front, and not engine front
2. Safari DICOR
Now issues here also have been mostly unrelated to DICOR per se. There have been injector changes in many 2.2s. And now there is a software fix. The problem was that service light with rail pressure error code used to come frequently, and only fix was injector change. However the service light used to come because the tolerances in software were much less than the injection system was designed for. So this service light which caused absolutely no issues in driveability caused a lot of grief to the users as well as tata as they had to replace perfectly working injectors. With new software this issue is solved.

Apart from that, there have not been any issues with engine in any 2.2. Some older ones had timing belt break issues, which was also fixed with a retro. Mine is the only safari with a problem thats not solved(idle hunting). Again this is a one off issue, and not really a DICOR issue.
The other problems in my car(brakes sliding, 4x4 hub failure etc., etc.,) have all been related to other components and not the DICOR engine.
Even the 2 breakdows where we were stranded were related to radiator leakage and temp sensor failure.

So there is no problem with DICOR. The problem is with TATA QC which is not at par with others. Thats why you have stuff like tie rods failing etc, etc.,

Tata QC(or lack of it) has been done to death, and most people are aware that when you get into TATA you get a VFM product, albeit with more niggles than the competition.

So do you think the dicor engines have a future in tata products?

will there be a 1.4 dicor in the new indigo vista with 90 horses? sid's old thread about it mentions 75 for the dicor.

I hope that the answers to both these questions are yes

Btw, is tata still continuing to work with delphi for these? they were supposed to be working with bosch for the nano powerplant, which will make it a proper CRDI. Or are both these engines being developed

Even I have a 2007 DICOR Marina and have so far not faced any reliablity issues with the engine at all. Yes its a TAD expensive to maintain but then the amount of power (if you keep it in the right power band) and the NVH levels are anyhting to compare its miles better than its TDI sibling.

TATA has always had only one problem- quality control/maintenance/implementation

Greenhorn, you mentioned the possibility of Tata doing something to Fiat which they already did earlier with Mercedes. What was that about?

If others don't face the issues that steeroid () and tsk faced, then why the gripe? That is 2 vehicles out of a few tens of thousands, right? I think only tsk had faced injection / injector issues, but that was not because of DICOR.

Oy, are you cocking a snook at the others because you have a TCIC engine? Cost effectivess is related to Total Cost of Ownership, which apart from investment includes a lot of other tangible and intangible benefits. By your logic, a Ferrari, Jaguar or a Land/Range rover - with their myriad problems - would be even less cost effective, right?

DiCOR - What went wrong?

At the end of 2 pages I still can't figure out what went wrong? What? How? Where? Show me?
C'mon lets beat up Tata ...

I'm unable to cite a source now. I recall reading this in an old issue of auto india. Is related to tata's first engine, and consequent parting of ways with Mercedes benz

@ jay. I'm not beating up tata. Just wondering where all the vehicles which were launched as Dicors are now being relaunched in turbo guise. Wasnt dicor supposed to be the future ?

You must be referring to the 60's TMB truck engine, but why the exhumation in the context with DICOR? IMHO what Tata is doing for FIAT today is quite commendable in industry context.

Sorry to drag off topic, but, Tata estate was almost an exact replica (exterior) of some Merc Model. I am sure they were associated with MB in more than 1 ways and had the part ways later.

Interesting thread..

@greenhorn.. I agree to the points you have made.

DICOR technology implemeneted by TATA is extremely weak. 99% of the guys at workshops with whom I have interacted were against DICOR tech of tata citing too many issues with electronic gizmos and thats where TDI of TML excels.. extremely maintainance free.

There are far too many aspects involved in DICOR for tata's to handle them well in professional manner unlike the competition.

Their QC is the real road block as far as my personal opinion goes.

There are quite a few vehicles (dicor) which are lying in workshops across india pertaining to electronic issues, FIP etc etc which we on this forum dont know, do we..And the only ones which we know on this forum, are the ones we all share across. Dont we ?

Ask the DICOR family vehicle owners on this forum, who drive this family of vehicles everyday pertaining to niggle & expensive maintainence of the same to come to a real analysis of the problems. That figure wont even count beyond 5% of the total dicors sold across india IMHO.

Reliability & Quality adherence is the main issue, whether its DICOR or TDI, which TML still has to catch up.

This thread is about Tata opting for a better engine, the Fiat multijet, rather than its own Dicor.. right? Then why are we comparing it with the TDI?

Really ???

I guess its a win-win situation for both FIAT and TATA... but TATA can any day kick fiat off the hook ... i hope that day is not around soon.
i always feel indica is an inch to inch copy of punto+ fiat.. most parts fit indica without modification. Now dont say palio is a copy of indica ..
