3. About the Company:
VST Grandeur is a premier dealership launched by the Rs. 3000 Cr. VST GROUP,
representing Jaguar and Land Rover across Tamil Nadu. They operate from a 8,000 sq.
feet showroom in the heart of Chennai, that showcases luxury sedans from Jaguar and
premium SUVs from Land Rover.
The business is supported by state of the art after-sales facility located in the Guindy
Industrial Estate. The workshop provides more than 19,000 square feet of floor space
with 14 service bays. The fully equipped facility has all the required diagnostic
equipment, along with a dust-free aluminum repair body shop and paint-booth operated
by JLR trained and certified technicians.
Apart from the grandeur the VST group is involved in a plethora of ventures including
brands such as Honda, Bajaj and Ford

4. Introduction:
The service sectors form a major part of the automobile industry. Dealing with the
customer end, this sector is vital in understanding the problems and also obtaining a
feedback from the customer.
Unlike the Manufacturing sector, the service sector requires technical as well as in-depth
management skills. Customer satisfaction plays a key role irrespective of the complexity
of the problem.
The JLR service station receives varying complaints: regular service check up, wheel
wobbling, wheel pulling, and low pick up, ineffective air conditioning system and break
downs.
In case of break downs, the technicians attend the problems in person and rectify or
retrieve the vehicle back to the workshop depending on its feasibility.
The service station is kept up to date and follows kaizen (continual improvement). The
time card system follows helps the management track the efficiency and time taken for a
particular job, in turn maintaining quality and standards. Regular Audits also ensure the
required amenities are in place.
With all the facilities available and constantly inflow of cars for repair, JLR service
station proved to be a vast resource for practical knowledge.
The month long internship involved assessing time cards, understanding quality
procedures, hands on learning of the vitals of a car and also regular service procedure.

5. Observation:
1) Operational Procedure:
1. The vehicle is received by the service advisor.
2. A basic inspection is noted down by the advisor on the job car majorly, noting
down the dents scratches and other details as the VIN number of the car.
3. Following the inspection a pre road test is performed to inspect and understand
customer complaints.
4. The complaints are noted down and are systematically described in the job card.
5. The Job Card is then passed onto the floor in charge.
6. As per the technician skills and availability the job cards are dispatched to the
respective technicians.
7. Analyzing the problem, the technicians obtain estimates for parts from the
inventory and await customer approval (not in case of warranty).
8. On customer approval the technicians obtain the parts and continue their
processes.
9. In most cases the technicians refer Topix to obtain solution and given standard
procedures.
10. The technicians are expected to time every task they perform and hence the start
and stop timings are printed on the job cards.
11. On completing the assigned tasks the technicians give a brief write up about the
problem solved.
12. The vehicle is then taken for a road test to ensure the complaints are completely
arrested and further sent to water wash.
13. The Quality report is updated after a particular vehicle is completed.

6. 2) Service Check up:
The service check up is mandatory once in 6 months or 12000 kms. The service is
classified into two types: Type A and Type B
Type A:
The service type A involves replacement of three, major filters: Engine Air filter, Pollen/
A.C filter and Oil Filter. The Engine Oil is drained and replaced (Grade 5W-30: Diesel
Grade5W-20: Petrol).
The washer fluid is refilled and water is topped up, the brake pads are checked for wear
and tear if they are below permissible limits they are recommended for replacements.
Type B:
The service type B involves replacement of fuel filter apart from the regular Type A
components. The fuel filter separates moisture and other impurities present in the fuel and
also returns excess fuel in the fuel line to the tank.
In case the customer report wobbling and pulling of the vehicle towards a particular side,
Wheel Balancing and Alignment is performed on the vehicle.

7. 3) Refrigeration System:
The increase in heat during summer has made air conditioning mandatory, several
complaints had been received due to insufficient cooling.
The Refrigerant R134A (chlorofluoroethane) is used in vehicles. This refrigerant stands
out since it is not harmful to the environment though it is not as efficient as R22.
Since R134A being very corrosive it has a tendency to erode the tube lines and cause gas
leaks, hence a new alternative HF01234yf will be adopted in the near future.
In vehicles with air conditioning defects, the refrigerant is drained and replaced using the
Robin air machine .Recharging is done in the compressor inlet line or evaporator outlet
line. Quantities of 700-880 gms of refrigerant are replaces as per the specification.
If the problem is not arrested, the output temperature is checked if its within permissible
limit (6 degrees). If not the compressor is replaced.
A general refrigeration system involves the following processes:
 Isentropic Compression
 Condensation (P=Constant)
 Expansion (Enthalpy = Constant)
 Vaporization (P=Constant)

8. Other Minor Observations:
Poor performance of the vehicle can be narrowed down to leak or cracks in the air inlet
hose or the turbo charger might have been affected. Turbochargers are forced induction
systems, they compress air on inlet of engine and hence increase power to weight ratio
thus giving a better performance.
Turbochargers are differentiated from superchargers since they are powered by mass flow
of exhaust gas driving the turbine, while superchargers are powered mechanically by belt
drives from engine crankshaft.
In case the fuel filter is blocked, similar issues might be present.

9. Conclusion:
The service sector proves to be a supportive leg and involves immense technical
expertise. The experienced technicians and staffs enable proper functioning of the service
station.
Each car is unique and the station faces a wide range of challenges. The efficient
management and cooperation enables them to tackle these tasks with ease.
Even a day in the workshop will prove to be worthy and a very good learning experience.
The wide variety of cars available portray the advancement in technology and features
present.
Reflection on the internship :
The internship has been very fruitful and I thank the management for this opportunity. I
also owe a lot to the technicians and staff who were more than willing to help. I believe
the internship has made my stronger and more confident. Studying the vehicles up close
has improved my technical understanding and also the hardships on the field.
The hands on practice and working procedure gave me an insight on repairs and I'm
confident that in the future I can repair my own vehicle and also analyze.
I'm sure this internship will have a positive influence on my projects to come I hope to
have better association with the company in the future .
